    Resources for the physics of clouds

    Does anyone know of any good papers/lectures/textbooks/etc that discuss the physical and mathematical principles that explain the structure and motion of clouds? Thanks.

    Exploring Motion in Physics: Beyond Translation, Rotation, and Oscillation

    In high school I learned about three kinds of motion in classical mechanics - translation, rotation, and oscillation. Are there any other kinds of motion in the physical world?

    Can Heat Transfer Through Conduction Occur at Relativistic Speeds?

    Are there any known instances of heat transfer via conduction or convection happening at relativistic speeds? Is this even possible or is there a non-relativistic limit to how fast heat can transfer in these ways, like how sound can only move so fast?

    I Why does wind blow leaves in circles?

    Earlier today I realized that, when a strong gust of wind would blow through my area, it would pick up leaves off the ground and typically blow them in circular patterns, and typically the leaves would go in at least several complete circles before coming to rest back down on the ground. Why is...

    B Why are serrated knives more effective than normal knives?

    What physical processes does serration take advantage of that make cutting something with a serrated knife more effective than cutting something with an ordinary knife? What is the optimal shape of each tiny segment of a serrated knife? Would cutting effectiveness increase as you add more...

    Does Teaching by Numbers Limit Understanding of Elasticity in Rubber Bands?

    If you take a rubber band and fix it in a stretched position for an extended period of time, would it eventually lose its elasticity? If yes, then how can you calculate how long it would take until its elasticity decreases by a certain amount, say, fifty percent? If no, why not? How does the...

    Stargazing Planetary orbits -- Why do planets orbit at same “level”?

    Why is it that all of the planets in our solar system (to our knowledge) orbit the sun in such a way that they all go around the sun in roughly similar orbital planes? Why don’t we have planets with orbital planes at significantly different angles?

    Classical Analyze Dampened Oscillations in Fluids: Math & Physics

    I am a layman with very little experience in math and physics and recently I became curious about how to analyze dampened oscillations occurring in fluid mediums, such as those following a disturbance in a pool of water. What sort of math and physics is required to understand this phenomenon and...

    Calculating the amplitude of waves in water

    I'll be honest, I have no idea. I haven't really studied waves since high school, and that was only a basic, 2D overview of EM waves. But still, I'll take a guess: maybe we assume the surface waves are something along the lines of frictionless, or they propagate without being dragged by the air...

    Calculating the amplitude of waves in water

    Suppose I have a perfectly circular pool which is four meters in radius, two meters in depth, and filled with water. Say I drop a steel ball with a radius of five centimeters into the middle of the pool from a height of five meters above the water's surface. After three seconds, what will be the...

    Question for STEM high school teachers — What do you like and dislike?

    Maybe if someone creates their own question inquiring about what it’s like to be a student in a high school STEM class, I will. But for now, I would like answers from the teacher’s perspective.

    Translational and rotational velocity

    R is the radius yes and by tangential velocity I mean the linear velocity of a point on the edge of the cylinder.
